In fear and trembling we are saved

Here are two thought provoking questions:
Is it possible for those who think they are not saved to be saved?
Is it possible for those who think they are saved to not be saved?

God's word is complete regarding our faith.
In one sense, salvation by grace through faith alone is a great truth, but on the other hand, doing good works is a must in a Christian's life. If we have no works and still live as unrighteous and sinful as before, we are deceiving ourselves and have no part in the kingdom.

Interestingly, the Apostle Paul wrote as much, if not more about how a Christian ought to live and act in this life as being saved by faith alone. (you can see this if you read his letters to the Corinthians, Galatians chapter 5, Ephesians 5, Romans, even Jesus says that those who love him obeys his commandments, those who do not bear fruit will be cut off and burned, those who are wicked will be thrown into the darkness where there will be weeping and gnashing of teeth etc...)

I do not write this to scare people or make them feel guilty, but we are called to be sober minded, Brothers and sisters, do not be deceived by the teachings of this world to conform to it's patterns. Do not go after things like status in school and in work, seeking honour from men, money, pleasure, sex, competition, laziness, and youthful passions for fun and games, but pursue Christ and seek to know him, seek to become holy and virtuous people who live with honor, truth, love, kindness, gentleness, and patience(This is a lifelong process of sorrow, hardship, and much struggling with flesh and sin). For Christ is the one whom we need to believe, not theology or ideas about him. These things are dead, and there is so much more to learn in Christ than justification through faith alone, because Christ is alive and is our life.

Constantly check to see if you are still in the faith, working out our salvation with fear and trembling for it is God who works and wills within us. As Paul Washer puts it, this life is like a mine field, we cannot make it out alive unless we listen to God and obey him.
